C++ final and override keywords are not correctly identified

The C++11 specifiers final and override are missing in the C++ syntax file.
They are context specific keywords, so they must not always be classified as a keyword.

Ironically they are present in the C syntax file with some checks for the correct context.
This check fails for some cases though. These three are currently missing in Code:

class deriv final : base {
    void meth1() final;
    void meth2() override;
}

• final and override in class declarations
• final classes ... GitHub seems to be missing that one too 😄
